You simply inject the inside of the anemone with some lemon juice. Hopefully they'll die off. Above all don't try to pull them off the rocks. They will just grow back & spread. Normally they are hitchhikers on rock. Don't know how many you have in your tank or the size of it. I had a number of them in my tank - 1 shrimp cleaned them up & I haven't seen one since. Not aware of any other clean-up crew that finds them tasty.
